使用 \if 修改坐标附近的节点

使用 \if 修改坐标附近的节点

我想编写类似这样的代码：

if \thecitation is {This work} then
    nodes near coords={\thenumber{} [This work]} and plot color is Red
else
    nodes near coords={\thenumber{} \cite{\thecitation}} and plot color is Blue

这是我使用的代码：

\begin{filecontents*}{RR.dat}
y   x   Label   Cite
1   0.613   PSB Jung:2015
2   -1.700  MRB Jung:2015
3   0.998   BC700   {This work}
4   0.903   BC600   {This work}
5   0.891   BC500   {This work}
6   0.759   BC400   {This work}
7   0.030   BG450   Yao:2012
8   -0.050  BB450   Yao:2012
9   0.381   TC600   Zeng:2013
10  0.018   PC700   Zeng:2013
11  0.667   SBT Zhang:2012
\end{filecontents*}

    \begin{tikzpicture}
    \begin{axis}[
        axis lines*=middle,
        yticklabels from table={RR.dat}{Label},
        ytick=data,
        yticklabel style={xshift=-4cm},
        nodes near coords={\thenumber{} \cite{\thecitation}},
        nodes near coords align={horizontal},
        visualization depends on={value 2.1cm*(-\thisrow{x}+max(0,\thisrow{x})) \as \myshift},
        every node near coord/.append style={xshift=\myshift},
        visualization depends on={value \thisrow{Cite} \as \thecitation},
        visualization depends on={value \thisrow{x} \as \thenumber},
        ]
        \addplot+[xcomb] table [x=x, y=y] {RR.dat};
    \end{axis}
    \end{tikzpicture}

结果如下： 在此处输入图片描述

解决了：

答案1

以下是此次合作斯蒂法诺和我放在一起。然而，它也去掉了这项工作条目，我不知道这是否是我们需要的。

提示：如果从第一个图中删除discard if样式，标签可以正确显示。但是，红色条目会覆盖之前的蓝色条目，这可能会导致打印效果不佳，因此效果不是最佳。
